Abstract
A circuit for connecting a voltage source to a load is provided. The circuit may include a Vbatt node configured to be connected to a voltage source and a diode electrically connected with the Vbatt node. A battery isolation switch module is electrically connected with the diode, the diode being arranged in series between the battery isolation switch module and the Vbatt node. A capacitor bank is electrically connected with the battery isolation switch module and to ground. The capacitor bank is configured to be further connected with a microprocessor power supply. A high side driver may be configured to receive power from the voltage source. The diode is configured to isolate the capacitor bank and the power supply. The diode is arranged to prevent current from flowing back through the diode from the battery isolation switch module and the capacitor bank to the Vbatt node or HSD output.
